Combination of all possible row cases

I am trying to create a program to generate all possible cases of string capitalization in python. For example, given "abcedfghij", I want the program to create: ABCDEFGHIJ ABCDEF ..,, ABCDEF .., ABCDEFGHIJ

Etc. I'm trying to find a quick way to do this, but I don't know where to start.

from itertools import product, izip def Cc(s): s = s.lower() for p in product(*[(0,1)]*len(s)): yield ''.join( c.upper() if t else c for t,c in izip(p,s)) print list(Cc("Dan"))

prints:

 ['dan', 'daN', 'dAn', 'dAN', 'Dan', 'DaN', 'DAn', 'DAN']

Similar to Dan's solution, but much simpler:

 >>> import itertools >>> def cc(s): ... return (''.join(t) for t in itertools.product(*zip(s.lower(), s.upper()))) ... >>> print list(cc('dan')) 
  ['dan', 'daN', 'dAn', 'dAN', 'Dan', 'DaN', 'DAn', 'DAN']

 import itertools def comb_gen(iterable): #Generate all combinations of items in iterable for r in range(len(iterable)+1): for i in itertools.combinations(iterable, r): yield i def upper_by_index(s, indexes): #return a string which characters specified in indexes is uppered return "".join( i.upper() if index in indexes else i for index, i in enumerate(s) ) my_string = "abcd" for i in comb_gen(range(len(my_string))): print(upper_by_index(my_string, i))

Of:

 abcd Abcd aBcd abCd abcD ABcd AbCd AbcD aBCd aBcD abCD ABCd ABcD AbCD aBCD ABCD
